I have a problem with my 'Imperial Elite Chip Fryer IFS-40'. When the oil in the fryer has reached its desired temperature, the gas valve is meant to completely switch off. The problem I am experiencing is that once the oil has reached its peak, a tiny flame is consistent through out its use. Does this mean that the valve is faulty? Or could a part in the valve be faulty? .

Sounds like the pilot is dirty,if you have propane gas this is your issue,replace the pilot either way.

Is this fryer propane?It sounds like the baffles in the tank are clogged.If you remove a burner shine a light in the baffle,if you see alot of soot use a shop vac and clean it out.Let me know.

SOURCE: flame not going into heat tubes

Make sure the regulator assembly on the gas valve is for propane. Sounds like the gas pressure is too low and the flames aren't going into the burner tubes. Make sure they didn't install an appliance regulator on the back of the fryer. This is not needed as the fryer has a regulator on the gas valve. You can unscrew the cap on the regulator assembly and turn the plastic screw inside all the way in. DO not turn with alot of force. Easy does it.
